Apple Training Series: Mac OS X System Administration Reference, Volume 1

He's got an amazing grasp of the subject and very easy, organized way to present it. I'm enjoying learning what could otherwise be a very dry subject.

I read this book from cover to cover in order to prepare for two of the ACSA certification exams Apple offers, including the Directory Services Integration and Administration and Best Security Practices exams. If one is interested in the topics then one can learn an amazing amount of details and facts, otherwise difficult to come by in such an easily readable style. However, I should warn, the book is not perfect in that the quality of the exposition can vary greatly from chapter to chapter. If I recall correctly, one of the first chapters explaining the basics of the KDC service and the concepts of Realms and principals contained grammatical errors so severe that they compromised the validity of the topic. Furthermore, some very interesting topics, such as cross realm authentication are barely touched upon. Also, the information herein will not really help one troubleshoot a problematic service/server, but it will give you the background information, provided you are actively absorbing the information, which will allow you to analyze and think through troubleshooting scenarios. However, any of these pitfalls are made up through such step by step explanations of the background processes behind promoting a server to an OD master, for example. I wish more OS books would cover such information either in this way or even at all. Regardless, the book definitely did an amazing job of preparing me for the exams. I received very high scores on both exams (a 96 on the Directory Services and an 88 on the Security exam) and learned numerous interesting facts in every chapter. At last, I would surely recommend this book for anyone thinking of getting an ACSA or someone just curious about the Unix side, along with its many possibilities, of OS X.[.....]

I bought this book along with Mac OS X Server Essentials. While that book is good on the GUI interface, this book shows in good detail what is really going on under the hood and behind the scenes. I have a much better understanding of Open Directory and LDAP in general as well as Kerberos and Single Sign in logic. Many of the other services offered under OS X Server 10.4 are also explained well. The command line information is good while not being so in depth as to lose the reader. You should have a basic familiarity with UNIX command line before trying to understand the concepts presented. The section on security is very good and presents a broad range of options to the administrator.

As another review states, this book is the guide for the relevant Apple ACSA courses. It succinctly provides you with an understanding of the basic information needed to attack the certification exams. I do also recommend that you find the time and funds to actually take the classes. The folks in Cupertino have put a lot of work into creating great courses that offer you the crucial opportunity to learn by doing. The content and examples you work through during the courses are relevant to a wide range of applications, from small business to multi-national corporation as well as K-12, higher education, and research. Schoun himself is one of the top independent providers of Apple training and has had no small hand in the development of the courses. I've had the pleasure of taking classes from him on several occasions and recommend his work highly.

This book is a one-to-one version of the course material found in the Directory Services Integration and Administration v10.4 course, the Security Best Practices v10.4 course and more. The exercises are well thought out and easy to do. Not so easy to remember are the 800+ pages, but it is not meant to teach you all you need to know about being an SysAdmin. It is enough to get you through these two exams, which give you 7 credits and the ACSA. And it is enough to set you off into a job as Junior SysAdmin or, as in my case, a supporter with server duties. Ideally, one should visit both official courses - not so much because more is offered in the actual courses than in the book, but rather because one can ask pointed questions of the teacher, that one cannot ask if something in the book is not clear. As in most such books, it represents a beginning - the rest is a matter of acquiring experience. Do not expect this book to give you all the answers. I doubt if that would be possible. But it will give a whole lot of things to look out for and a whole lot of new input, especially if you have been doing some SysAdmin-ing and now want a look-see as to how the fulltime SysAdmins do it.
